Patent number: 9170572Abstract: A method of dynamic model selection for hybrid linear/non-linear process control includes developing a plurality of process models including at least one linear process model and at least one non-linear process model from inputs including dynamic process data from a processing system that runs a physical process. At least two of the plurality of process models are selected based on a performance comparison based on at least one metric, wherein the selected process models number less than a number of the plurality of process models received. A multi-model controller is generated that includes the selected process models. The physical process is simulated using the multi-model controller by applying the selected process models to obtain closed loop performance test data for each of the selected models. The performance test data is compared. A selected process model is then selected.Type: GrantFiled: July 6, 2011Date of Patent: October 27, 2015Assignee: Honeywell International Inc.Inventors: Ward MacArthur, Sriram Hallihole, Ranganathan Srinivasan, Madhukar Madhavamurthy Gundappa, Mandar Subhash Vartak, Gobinath Pandurangan, S.
